Definitions
- the claimed invention relates to a calibrated replaceable alcohol sensor module for use with a Breath Alcohol Testing Device. More specifically, this invention describes an alcohol sensor module that can be removed from the body of a breathalyzer and separately calibrated for the accurate calculation of "percent blood alcohol concentration” (%BAC) based on breath air samples, and then re-installed into the breath alcohol tester.
- %BAC percent blood alcohol concentration
- the Breath Alcohol Testing Device is also commonly called a “breathalyser” or a “breathalyzer” (hereinafter breathalyzer), and includes both portable (PBT or Portable Breath Tester) and stationary (coin-operated or similar) units.
- the claimed invention remedies this situation by providing a method to calibrate (or re-calibrate) the breathalyzer that greatly reduces or even eliminates the time and cost involved in shipping and handling of breathalyzers and maintenance of service centers, as well as the time and utility lost by the end user.
- a typical breathalyzer consists primarily of an alcohol sensor component, signal processing unit (or CPU) 150, and a display unit 140 to show results.
- a breath alcohol sensor is calibrated to match select calibration points using standard specifications (controlled alcohol mixtures), and the signal processing unit (or CPU) determines BAC based on linear calculation using the calibration points.
- every breath alcohol sensor will require re- calibration as undesirable residue and foreign substances including, but not limited to, saliva, cigarette smoke residue and food particles, become trapped inside the sensor.
- the current system of calibration (or re-calibration) of breathalyzers by service centers takes place when a consumer or end user, with a breathalyzer in need of calibration, contacts a breathalyzer retailer.
- the retailer directs the end user to ship the breathalyzer to an appropriate service center location.
- the service center uses controlled alcohol mixtures in order to re-calibrate the device according to standard specifications.
- the breathalyzer is shipped back to the end user.
- This procedure for re-calibration is time-consuming and costly in terms of shipping and handling of packages, labor hours and lost utility for the end user.
- There are currently over 100 retailers (online and offline) and/or distributors sell breathalyzer units to consumers and end users, whereas fewer than ten (10) service center locations exist to perform traditional breathalyzer re-calibrations.
- the claimed invention proceeds upon the desirability of providing significant benefits for both the breathalyzer service centers and the end users by practically eliminating the loss of time and utility for end users and reducing the number of labor hours and shipping costs for service centers, all while introducing an effective solution at a cost no greater than the current service center system.
- the claimed invention comprises a calibrated (or calibrate-able) alcohol sensor module, which comprises at least an alcohol sensor and an adapter to provide an electronic link to the breathalyzer to communicate sensor readings.
- the calibrated alcohol sensor module of the claimed invention is useable by distributors, retailers, sellers, buyers and end users to replace or eliminate traditional methods of breathalyzer re-calibration with a much more effective and efficient solution at a cost no greater and often less than any current method of re-calibration.
- the alcohol sensor module of the claimed invention can be removed from the body of a breathalyzer and separately calibrated for the accurate calculation of "blood alcohol concentration” (BAC) based on breath air samples, and then re-installed into the breath alcohol tester.
- the sensor module comprises an alcohol sensor and an adapter to provide an electronic link to the breathalyzer to communicate sensor readings.
- the claimed invention brings significant benefits the breathalyzer industry by giving consumers and/or other end users a better solution for re-calibrating the breathalyzer.
- the claimed invention essentially eliminates the loss of time and utility for end users and reduces the number of labor hours and shipping costs for breathalyzer service centers.
- the claimed invention brings these significant benefits and solution to both end users and breathalyzer service centers at a cost that is no greater than the current service center system.
- the calibrated, replaceable alcohol sensor modules of the claimed invention enables the end users to purchase new sensor modules when the need arises at a cost no more than (and often less than) the cost for re-calibration service.
- New or calibrated sensor modules of the claimed invention ship with simple instructions for the end user to follow in order to manually replace the old sensor module requiring calibration. Because the sensor modules are pre-calibrated, shipment to the end user is immediate and without delay.
- the end users can purchase sensor modules simultaneously with the purchase of a breathalyzer or prior to the time that the old sensor requires re- calibration.
- the process of re-calibration with the sensor module of the claimed invention is simpler and faster than the current calibration system of utilizing a breathalyzer service center since the end user only needs to spend a few seconds swapping the old sensor module with a new sensor module in order to return the breathalyzer to its full functional use without delay.
- the claimed invention addresses all known and future breathalyzers (or other breath alcohol testing devices) because the replaceable sensor module can be made compatible with current and future breathalyzers (or other breath alcohol testing devices).
- the replaceable sensor module can be applied with minimal modification to various other portable electronic devices, as long as such devices having a processing unit processing sensor readings and a display capable of showing %BAC readings (e.g. digital LED display), such as portable radar detectors, portable GPS devices, mobile phones, electronic key/keychain devices, etc.
- a breathalyzer user (general consumer, owner or operator of a breathalyzer compatible with the claimed invention) can purchase or otherwise acquire a new sensor module in order to replace the old sensor module at minimal cost and time lost for all parties involved when the breathalyzer's sensor requires re-calibration.
- the traditional re-calibration system and procedure involves multiple transactions and/or communications among several entities.
- an end user generally consumer, owner or operator of a breathalyzer
- the large majority of all breathalyzer retailers are unable to perform re-calibration themselves, so either the retailer accepts breathalyzers requiring re- calibration from end users and ships them in bulk to a breathalyzer service center, or the retailer directs the end user to ship the breathalyzer requiring re-calibration directly to the service center.
- the claimed invention eliminates many of these aforementioned problems associated with the current re-calibration system and methodology by removing entirely the need for record-keeping, processing and shipping of calibrated breathalyzers beyond the common retail practice of stocking the replaceable sensor modules by the retailers and/or distributors. Delays, costs and problems associated with the current re-calibration system can be greatly reduced and even eliminated with the claimed invention. All breathalyzer service centers operate primarily as either breathalyzer distributors or retailers, and the service center portion of business does not generally generate significant income for these distributors or retailers, often creating a loss in profit. The claimed invention seeks to either greatly reduce the strain on the operation of these service centers or eliminate the need for service centers altogether.
- the breathalyzer market can be made more efficient and ready for uninterrupted growth.
- Calibrated replaceable sensor modules of the claimed invention will be made available to all parties involved in the breathalyzer transactions, thereby requiring only a single transaction (sale) with a single party for the end user to recalibrate a breathalyzer, in most cases.
- a processing unit e.g. a digital LED display
- the claimed invention can be incorporated into such portable electronic devices as portable radar detectors, portable GPS devices, mobile phones, electronic key/keychain devices, etc.

- a breath sampling tube 20 can be attached to the sensor module 60, as shown in Figs. 1 and 3, for those breathalyzers 100 requiring the breath sampling tube 20 for the breath alcohol sensor 11 to function properly.
- the claimed invention describes the sensor module 60 and the breath sampling tube 20 as separate components, because of the inevitable variation in and/or non-use of the breath sampling tubes 20 across various types of breathalyzer 100.
- "calibrated replaceable alcohol sensor module" or “sensor module” 60 may refer to the claimed invention with or without the attached breath sampling tube 20 and with or without the heating unit 13.
- a sensor module 60 in accordance with an exemplary embodiment of the claimed invention, comprising a printed circuit board (PCB) 10, an alcohol sensor 1 1 and an adapter 30 to electrically/electronically link the sensor module to a breathalyzer 100.
- the adapter 30 of the sensor module 60 communicates the sensor reading from the alcohol sensor 11 to the breathalyzer 100.
- the sensor module 60 can additional comprise a heating unit 13 and/or a breath sampling tube 20.
- the circuitry of the alcohol sensor 11 of the sensor module 60 is operable to detect changes in conductivity according to varying levels of alcohol concentration.
- the alcohol sensor 11 can be a fuel cell sensor, a semiconductor sensor and the like.
- a fuel cell sensor has a porous acid-electrolyte material between two platinum electrodes. As the breath sample flows past the fuel cell, the platinum oxidizes the alcohol in the breath sample to produce acetic acid, protons and electrons. The electrons flows from the platinum electrode of the alcohol sensor 1 1 to provide an electrical current, which is transmitted to the signal processing unit 150 of the breathalyzer 100 via the adapter 30 of the alcohol sensor 11.
- the electrical current produced by the alcohol sensor 1 1 is proportional to the amount of alcohol in the breath sample that is oxidized by the alcohol sensor 1 1.
- the processor or signal processing unit 150 of the breathalyzer 100 measures the electrical current and calculates BAC.
- the display 140 of the breathalyzer displays the calculated BAC.
- a semiconductor sensor is generally formed from a metal oxide, e.g., tin oxide.
- a metal oxide e.g., tin oxide.
- alcohol i.e., ethanol molecules
- the resistivity of the metal oxide thereby altering the current outputted by the semiconductor sensor. That is, when the ethanol molecules comes in contact with the metal oxide of the semiconductor sensor, the reaction changes the resistivity of the semiconductor sensor.
- the semiconductor sensor measures the changes in the resistivity caused by the breath sample. Such changes in the resistivity results in change in the output current, hence the semiconductor-based breathalyzer can measure the change in the resistivity or change in the current to calculate/estimate the BAC.
- certain alcohol sensor 11 e.g., a semiconductor sensor
- the optional heating unit 13 to warm the alcohol sensor 11 can be provided on the sensor module 60 or the optional heater 170 to warm the alcohol sensor 11 can be equipped in the breathalyzer 100.

- the sensor module 60 can include all components of a breathalyzer 100 that may suffer from residue build-up and other problems requiring re-calibration. This advantageously enables the claimed invention to provide a breathalyzer 100 that is as accurate as and functionally equivalent to a "new" breathalyzer 100 by simply replacing the sensor module 60 of the claimed invention.
- the primary cause for breathalyzer inaccuracy is sensor pollution, which refers to the build-up of sensor contaminants such as saliva, cigarette smoke, food particles, etc. This build-up of contaminants does not only cause sensor inaccuracy, but also reduces the overall lifetime of the sensor 11, because the residue cannot simply be removed. This means that even if the sensor is re-calibrated or adjusted, it can never be as efficient or accurate as a new sensor 1 1.
- the buildup of contaminants within the breath sampling tube 20 can also affect functionality and accuracy of the breath alcohol sensor 11 , but to a lesser extent than sensor pollution.
- the breath sampling tube 20 attaches to the sensor module 60, as shown in Figs. 1 and 3.

- the breath sampling tube 20 consists of a long cylindrical tube 21 for the blown air to travel through, a mouthpiece slot 27, and a bent or curved section 25 to direct air toward the alcohol sensor 1 1.
- the breath sampling tube 20 is shown as long cylindrical bent tube, it is appreciated that it can be any shape or length to accommodate different types of breathalyzers.
- Fig. 1 shows how the calibrated replaceable breath alcohol sensor module 60 can be installed into a compatible breathalyzer 100.
- the breath sampling tube 20 of the breathalyzer 100 is attached to the sensor 11 of the sensor module 60.
- the breath sampling tube 20 comprises an attachment slot 29 and the breathalyzer 100 comprises an attachment slot 120 to secure the sensor module 60 in the accessible compartment 110 of the breathalyzer 100.
- a cable 40 is shown in Fig. 1 to link the sensor module 60 to the breathalyzer's signal processing unit 150 via the adapter 30, the adapter 30 can link the sensor module 60 directly to the breathalyzer's signal processing unit 150.
